What Is A Hydraulic Oil Chiller?
ChillerOne hydraulic oil chiller is a special refrigeration device. It removes the heat of the working hydraulic oil through forced air cooling or water circulation heat exchange methods, which effectively prevents problems such as decreased viscosity, deteriorated lubrication performance, aging of seals and reduced system efficiency of the oil due to high temperature. This ensures the stable and reliable operation of your hydraulic equipment and extends its service life.
Working Principles of the Hydraulic Oil Chiller
- Step 1: The high-temperature hydraulic oil within the system transfers its heat to the coolant (water or ethylene glycol), which raises the temperature of the coolant while the hydraulic oil is initially cooled.
- Step 2: The coolant that has absorbed heat flows through the evaporator and undergoes efficient heat exchange with the low-temperature refrigerant. The refrigerant absorbs the heat of the coolant and evaporates into a gaseous state, while the coolant is cooled and recirculated to cool the hydraulic oil.
- Step 3: The gaseous refrigerant at low temperature and low pressure is extracted and compressed by the compressor, and then transformed into a high-temperature and high-pressure state.
- Step 4: The high-temperature and high-pressure refrigerant enters the condenser, where it is forcibly cooled by air or water to release the heat it carries into the external environment. At the same time, the refrigerant itself condenses into a high-pressure liquid.
- Step 5: The high-pressure liquid refrigerant flows through the expansion valve, where its pressure and temperature are sharply reduced, reverts to a low-temperature and low-pressure state that is prone to heat absorption, and then enters the evaporator to start a new cycle, thereby continuously providing cooling capacity for the system.
Types of Hydraulic Oil Chillers
Air Cooled Hydraulic Oil chiller
ChillerOne air cooled hydraulic oil chiller works by driving air through the finned heat dissipation core with a fan, forcing convection heat exchange with the hot hydraulic oil inside, and dissipating the oil temperature into the air.
- Advantages: It does not need to be connected to an external water source and can work simply by driving the fan with electricity, which is very easy to install and highly adaptable. In addition, its structure is relatively simple. For daily maintenance, you usually only need to clean the heat dissipation fins, and the long-term operation and maintenance costs are relatively low.
- Disadvantages: Its heat dissipation effect directly depends on the temperature and quality of the ambient air. At high temperatures, its cooling capacity will significantly decline. In addition, to achieve a heat dissipation effect comparable to that of water cooling, it usually requires a larger heat dissipation area, resulting in a larger volume. At the same time, the operation of the fan will generate considerable noise, which will have a certain impact on your working environment.
Water Cooled Hydraulic Oil Chiller
ChillerOne water cooled hydraulic oil chiller reduces the oil temperature by circulating cooling water flowing through the internal pipes of the heat exchanger and exchanging heat with the hot hydraulic oil flowing on the other side through the coil pipes.
- Advantages: Due to the fact that the specific heat capacity of water is much greater than that of air, its heat exchange efficiency is extremely high, capable of quickly removing a large amount of heat, and its cooling effect is almost unaffected by the ambient temperature. In addition, under the same heat dissipation capacity, water cooled chillers are usually much smaller in volume than air cooled chillers, and they operate very quietly during operation.
- Disadvantages: It usually requires the installation of facilities such as cooling towers and water pipes, resulting in relatively high initial investment and system complexity. In addition, scale is prone to form in the cooling water, which will reduce its efficiency and even clog the flow channels in the long term.
Features and Advantages of Hydraulic Oil Chillers
High-Efficiency Heat Exchange
Our hydraulic oil chiller features a compact structure design, typically adopting plate, shell and tube or finned tube designs. It has an extremely large heat exchange area and can achieve rapid heat transfer between the hydraulic oil and the cooling medium.
Sturdy and Durable
Our core components are made of materials with good thermal conductivity such as copper, stainless steel or aluminum. They can also withstand the working pressure of the hydraulic system, ensuring the reliability and durability of your hydraulic oil chillers.
Stable System
Our hydraulic oil chiller maintains the stability of the hydraulic oil viscosity by precisely controlling the temperature of the hydraulic oil, which ensures the accuracy and consistency of the working pressure, flow rate and actuator speed of your system, enhancing the overall operational stability and processing accuracy of your equipment.
Long Service Life
By using our hydraulic oil chiller, you can effectively prevent problems such as oxidation of hydraulic oil, decline in lubrication performance and premature aging of seals caused by excessively high oil temperature. It significantly extends the service life of hydraulic pumps, valves, seals and the hydraulic oil itself.
Improve Work Efficiency
Using a hydraulic oil chiller in your project can prevent thermal protection shutdown of the system due to excessively high temperatures and reduce internal leakage caused by improper oil viscosity, thereby increasing the continuous operation time of your equipment.
Reduce Maintenance Costs
Our hydraulic oil chiller significantly reduces the frequency of hydraulic oil replacement and machine maintenance during use by preventing high-temperature deterioration of the oil and abnormal wear of components, which fundamentally lowers the long-term operation and maintenance costs of your equipment.
Applications of Hydraulic Oil Chillers
Industrial Processing
In injection molding machines, die-casting machines and various types of machine tools, our hydraulic oil chillers ensure the stability and processing accuracy of your project’s long-term continuous production through precise temperature control, which effectively prevents the impact of oil temperature fluctuations on your product quality and production efficiency.
Engineering Field
For those mobile devices, our air cooled hydraulic oil chillers enable excavators, cranes and other construction machinery to operate continuously at high intensity under various harsh working conditions, which ensures the continuous and reliable power output of your hydraulic system.
Transportation Field
For hydraulic systems like those of ship deck machinery and heavy trucks, our hydraulic oil chillers provide stable thermal management for their critical hydraulic functions in harsh environments with limited space and frequent vibrations, which directly enhance their operational safety.
Energy Infrastructure
In large-scale equipment such as wind turbines, our hydraulic oil chillers shoulder the responsibility of withstanding extreme working conditions and huge heat loads, which ensures that these core infrastructures can operate continuously for long periods.
When you observe the following problems in your hydraulic system: the oil temperature remains consistently above 60℃, the actuator shows weakness or unstable speed, the hydraulic oil oxidizes and deteriorates prematurely and turns black, the seals frequently leak, or the equipment frequently stops due to high temperatures, you need to install or upgrade a cooler.
If you use our hydraulic oil chiller to cool the heat of the hydraulic oil during the operation of your machine tool, it can roughly keep its temperature between 10℃ and 50℃. It enables your machine tool to withstand high heat loads and discharge the heat from the hydraulic oil through specific temperature control.
Compared with traditional cooling methods that rely on natural heat dissipation from the oil tank surface or simply install fans, our hydraulic oil chiller can quickly transfer the heat from the high-temperature oil to the air or cooling water through a compact heat exchange core design and independently driven fans or water pumps, which achieves precise temperature control. This has completely overcome the drawback of low heat dissipation efficiency in traditional methods, providing a stable and reliable active heat dissipation guarantee for modern hydraulic systems.
When you choose a suitable hydraulic oil chiller, first you need to confirm the total heat generation of the system to match the cooler with the corresponding heat dissipation power. Secondly, you need to ensure that the chiller can withstand the system pressure and the pressure loss when the oil passes through is within the allowable range. The most important thing that cannot be ignored is that you must ensure the size of the cooler can be smoothly installed on your equipment mountain and can be connected to the existing pipelines.
Sure. Our professional engineering team can provide you with customized solutions from design to manufacturing based on your special space dimensions, ambient temperature, corrosive environment requirements or special flow and pressure requirements.
